Ruby on rails 为Gmail设置SMTP以使用RAILS创建“联系我们”页面时出错

我正在使用Rails设置

联系我们

表单。我想把表格上的内容邮寄到我的个人帐户。我按照前面提到的说明进行操作，当我运行

foreman start

时，出现以下错误

/home/adhithya/.rvm/gems/ruby-2.1.1@railstutorial_rails_4_0/gems/railties-4.0.4/lib/rails/railtie/configurable.rb:30:in `method_missing': undefined method `“smtp' for #<PersonalWebsite::Application:0x9b6e4c4> (NoMethodError)
from /home/adhithya/Desktop/RailsDev/rocky-oasis-9687/config/environments/development.rb:37:in `block in <top (required)>'
from /home/adhithya/.rvm/gems/ruby-2.1.1@railstutorial_rails_4_0/gems/railties-4.0.4/lib/rails/railtie/configurable.rb:24:in `class_eval'

最基本也是最简单的解决方案是：

#config/routes.rb
match "contact" => "welcome#contact", :as=> "contact", :via=>[:get,:post]


#controllers/welcome_controller.rb
def contact
   if(params[:name] && params[:message] && params[:email])
    NotificationsMailer.send_contact(params[:name] ,params[:email],params[:message]).deliver
    redirect_to root_path, notice: t('notice.welcome.contact')
  else
    render 'welcome/contact'
  end
end

#views/welcome/contact.html.haml
%form{:method => :post}
  %h2 Contact form
  %input{:type=>"hidden", :name=>"authenticity_token", :value=>form_authenticity_token.to_s}
  %div
    %label.control-label{:for=>"name"}
      Name
    %input{:name=>"name", :type=>"text", :required=>true, :maxlength => 50}
  %div
    %label{:for=>"email"}
      Email
    %input{:name=>"email", :type=>"email", :required=>true}

  %div
    %label.control-label{:for=>"message"}
      Message
    %textarea{:name=>"message", :id=>"message", :rows=>'5', :required=>true}

  %div.form-actions
    %input.button{:type=>"submit", :value=>"Send"}

#mailers/notifications_mailer.rb
def send_contact(name,email,message)
  @name=name
  @email = email
  @message = message
  mail(:subject=>"Message form contact form")
end

请粘贴development.rb文件（第37行附近），我刚刚编辑过它。我已经用我的开发更新了帖子。我想你在smtp设置上有问题。试试这个，我会用一个无表的模型来代替，并使用一个资源路由。你必须更改表单（资源的构建表单）和提交操作（更改参数名称）

#config/routes.rb
match "contact" => "welcome#contact", :as=> "contact", :via=>[:get,:post]


#controllers/welcome_controller.rb
def contact
   if(params[:name] && params[:message] && params[:email])
    NotificationsMailer.send_contact(params[:name] ,params[:email],params[:message]).deliver
    redirect_to root_path, notice: t('notice.welcome.contact')
  else
    render 'welcome/contact'
  end
end

#views/welcome/contact.html.haml
%form{:method => :post}
  %h2 Contact form
  %input{:type=>"hidden", :name=>"authenticity_token", :value=>form_authenticity_token.to_s}
  %div
    %label.control-label{:for=>"name"}
      Name
    %input{:name=>"name", :type=>"text", :required=>true, :maxlength => 50}
  %div
    %label{:for=>"email"}
      Email
    %input{:name=>"email", :type=>"email", :required=>true}

  %div
    %label.control-label{:for=>"message"}
      Message
    %textarea{:name=>"message", :id=>"message", :rows=>'5', :required=>true}

  %div.form-actions
    %input.button{:type=>"submit", :value=>"Send"}

#mailers/notifications_mailer.rb
def send_contact(name,email,message)
  @name=name
  @email = email
  @message = message
  mail(:subject=>"Message form contact form")
end
